During running build_native.py i get error "ExtensionMacros.h" no such file or directory.
The file itself is in cocos2d\extensions. I edited android.mk and uncommented line resposnsible for including this file. Why wont it find it?
Here is my android.mk:
LOCAL_PATH := $(call my-dir)

and the top of error source cpp file :

Does cocos2d/extensions/Android.mk have the line?
LOCAL_C_INCLUDES := $(LOCAL_PATH)/..
https://github.com/cocos2d/cocos2d-x/blob/v3/extensions/Android.mk#L40
It needs to find the header file.

first of all, I'm sorry for bad type English.
I want to compile an old source with NDK and cocos2d in windows.
this is my command line:

first, everything is compiling good, but after a few minutes, I give "arm-linux-androideabi-g++: error: CreateProcess: No such file or directory" error.
I searched on google, stack overflow, cocos2d forum, but no any any any result.
I'm confused.

Best Regards.
I'm new with Android so I don't fully understand how to make Android.mk files.
My project was running fine, following a tutorial online where the Android.mk was provided. But later on I needed to add a missing library and the tutorial for that had another Android.mk, now I'm trying to merge the two together.
Here is my Android.mk :
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
#opencv
OPENCVROOT:= C:\OpenCV-2.4.10-android-sdk
OPENCV_CAMERA_MODULES:=on
OPENCV_INSTALL_MODULES:=on
OPENCV_LIB_TYPE:=SHARED
include ${OPENCVROOT}/sdk/native/jni/OpenCV.mk
LOCAL_SRC_FILES := com_example_adrien_ndkopencvtest4_OpencvNativeClass.cpp
LOCAL_LDLIBS += -llog
LOCAL_MODULE := MyOpencvLibs
include $(BUILD_SHARED_LIBRARY)
Here is the Android.mk I need to add :
LOCAL_PATH := $(call my-dir)
OPENCV_PATH := D:/CODE/OpenCV-2.4.10-android-sdk/sdk/native/jni
include $(CLEAR_VARS)
LOCAL_MODULE := nonfree
LOCAL_SRC_FILES := libnonfree.so
include $(PREBUILT_SHARED_LIBRARY)
include $(CLEAR_VARS)
OPENCV_INSTALL_MODULES := on
OPENCV_CAMERA_MODULES := off
include $(OPENCV_PATH)/OpenCV.mk
LOCAL_C_INCLUDES := \
$(LOCAL_PATH) \
$(OPENCV_PATH)/include
LOCAL_SRC_FILES := \
nonfree_jni.cpp
LOCAL_MODULE := nonfree_demo
LOCAL_CFLAGS := -Werror -O3 -ffast-math
LOCAL_LDLIBS := -llog -ldl
LOCAL_SHARED_LIBRARIES += nonfree
include $(BUILD_SHARED_LIBRARY)
What I'm interested in in the last Android.mk is the libnonfree.so only, I don't need the cpp file.
Here is the structure of my project :
EDIT :
Thanks for your answers. I've done what was suggested and my Android.mk looks like that now :
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
#opencv
OPENCVROOT:= C:\OpenCV-2.4.10-android-sdk
OPENCV_CAMERA_MODULES:=on
OPENCV_INSTALL_MODULES:=on
OPENCV_LIB_TYPE:=SHARED
include ${OPENCVROOT}/sdk/native/jni/OpenCV.mk
LOCAL_SRC_FILES := com_example_adrien_ndkopencvtest4_OpencvNativeClass.cpp
LOCAL_LDLIBS += -llog
LOCAL_SHARED_LIBRARIES += nonfree
LOCAL_MODULE := MyOpencvLibs
include $(BUILD_SHARED_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := nonfree
LOCAL_SRC_FILES := libnonfree.so
include $(PREBUILT_SHARED_LIBRARY)
But the problem remains. I've got "Undefined reference" to methods libnonfree.so should add. I assumed the problem was from the Android.mk but maybe it's from elsewhere then.
I've added System.loadLibrary("nonfree"); to my MainACtivity and
#include "opencv2/nonfree/nonfree.hpp"
#include "opencv2/nonfree/features2d.hpp"
I don't know what I'm doing wrong.
EDIT 2 :
Here is the error :

SOLUTION :
My libnonfree.so file was not correct, I downloaded another one. I also changed my Application.mk file to :
APP_STL := gnustl_static
APP_CPPFLAGS := -frtti -fexceptions
APP_ABI := armeabi-v7a
APP_PLATFORM := android-16
If you want to add a prebuilt shared library to your project, you don't need a separate Android.mk
Let's take your script,
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
#opencv
OPENCVROOT:= C:\OpenCV-2.4.10-android-sdk
OPENCV_CAMERA_MODULES:=on
OPENCV_INSTALL_MODULES:=on
OPENCV_LIB_TYPE:=SHARED
include ${OPENCVROOT}/sdk/native/jni/OpenCV.mk
LOCAL_SRC_FILES := com_example_adrien_ndkopencvtest4_OpencvNativeClass.cpp
LOCAL_LDLIBS += -llog
LOCAL_MODULE := MyOpencvLibs
include $(BUILD_SHARED_LIBRARY)
and simply add to the bottom the extra module you need:
include $(CLEAR_VARS)
LOCAL_MODULE := nonfree
LOCAL_SRC_FILES := libnonfree.so
include $(PREBUILT_SHARED_LIBRARY)
Now the file C:\Users\Adrien\AndroidStudioProjects\NDKOpencvTest4\app\src\main\jni\libnonfree.so will be packed into your APK.
If you need this library to link your libMyOpencvLibs.so (this means, if your code in com_example_adrien_ndkopencvtest4_OpencvNativeClass.cpp uses some functions exported from libnonfree.so, you should also refeence it in your module:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
#opencv
OPENCVROOT:= C:\OpenCV-2.4.10-android-sdk
OPENCV_CAMERA_MODULES:=on
OPENCV_INSTALL_MODULES:=on
OPENCV_LIB_TYPE:=SHARED
include ${OPENCVROOT}/sdk/native/jni/OpenCV.mk
LOCAL_SRC_FILES := com_example_adrien_ndkopencvtest4_OpencvNativeClass.cpp
LOCAL_LDLIBS += -llog
LOCAL_SHARED_LIBRARIES += nonfree
LOCAL_MODULE := MyOpencvLibs
include $(BUILD_SHARED_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := nonfree
LOCAL_SRC_FILES := libnonfree.so
include $(PREBUILT_SHARED_LIBRARY)
Modify your android.mk as:
LOCAL_PATH := $(call my-dir)
OPENCV_PATH := D:/CODE/OpenCV-2.4.10-android-sdk/sdk/native/jni
include $(CLEAR_VARS)
LOCAL_MODULE := nonfree
LOCAL_SRC_FILES := libnonfree.so
include $(PREBUILT_SHARED_LIBRARY)
include $(CLEAR_VARS)
#opencv
OPENCVROOT:= C:\OpenCV-2.4.10-android-sdk
OPENCV_CAMERA_MODULES:=on
OPENCV_INSTALL_MODULES:=on
OPENCV_LIB_TYPE:=SHARED
include ${OPENCVROOT}/sdk/native/jni/OpenCV.mk
LOCAL_SRC_FILES := com_example_adrien_ndkopencvtest4_OpencvNativeClass.cpp
LOCAL_SHARED_LIBRARIES += nonfree
LOCAL_LDLIBS += -llog
LOCAL_MODULE := MyOpencvLibs
include $(BUILD_SHARED_LIBRARY)
Here the prebuild library i.e. libnonfree.so is declared in the android.mk, and referenced to it later via
LOCAL_SHARED_LIBRARIES += nonfree
Now to use it you need to load the latest built library in yout MainActivity i.e.
System.loadLibrary("MyOpencvLibs");
Thats it, now you have merged both the android.mk files into a new module named: MyOpencvLibs
For better understanding you can read my blog : https://androidtutsweb.wordpress.com/2017/04/04/android-mk-for-ndk-build-using-pre-build-libraries/
I m new to SDL, i have a problem to compile my project example i have:
#include "SDL_config.h" //(in red)
if i change it to:
#include "../include/SDL_config.h" //(it became green)

how to call a c function in the C++ function with the same name?
calling 'extern "c"' to use c header and "::"operation to use the c function,
but the link error occur.
my code:
extern "C" {
#include <libavcodec/avcodec.h>
}
...
class DllAvCodec
{
public:
...
virtual void av_free_packet(AVPacket *pkt) { ::av_free_packet(pkt); }
...
}
the error:
D:/player/jni/lib/DllAvCodec.h:143: error: undefined reference to 'av_free_packet(AVPacket*)'
why the code "::av_free_packet(pkt)" invoke undefined?

After a day and a half of modification I've finally gotten the VLC project to almost compile under OS X. I get the following error when its just about to link libvlcjni.so. There are roughly 100 more undefined references, but most are to few functions:
std::__stl_throw_length_error(char const*)
std::__node_alloc::_M_deallocate(void*, unsigned int)
Has anyone got any pointers?

Try to include these lines into your Application.mk:
APP_CPPFLAGS += -frtti
APP_CPPFLAGS += -fexceptions
You have to explicitly enable the RTTI and Exceptions handling.
EDIT (response to your modifications):
